Iran's President-elect Mahmoud Ahmadinejad renewed his allegiance with the late founder of the Islamic Revolution Imam Khomeini at his mausoleum in southern Tehran Sunday morning.

Accompanied by several members of his publicity office, Ahmadinejad laid a wreath of flowers on Imam's tomb just one day after scoring a landslide victory in the 9th presidential election.

The grandson of Imam, Hassan Khomeini, felicitated Ahmadinejad on his victory in the presidential race, IRNA reported.

Later he said that Iran needs nuclear technology for medical, scientific and engineering applications and would go ahead with its national nuclear program. "It is the right of the Iranian nation to move forward in all fields and acquire modern technology. Nuclear technology is the outcome of scientific progress of Iranian youth."

Ahmadinejad won the presidential seat Saturday, taking office as Iran's sixth president since the 1979 Islamic Revolution.
